How long after drinking fireball should i wait before taking hydrocodone for tooth pain?

Depends: I'd strongly advise against mixing the two drugs together. Alcohol can remain in the system even though you don't quite feel the effects and metabolism really depends on the individual, body weight, physical health, and if you have food in your stomach (because it changes the absorption rate). For a single 2 oz drink, it can take up to 2 hours to become completely metabolized.

Dangerous: Dangerous to mix alcohol and narcotic. Neither will cure tooth pain, only reduce severity until they wear off, at which time pain will come roaring back. Cause f the tooth pain (infection, fracture, etc) must be treated to obtain relief. Instead of self-medicating, call a Dentist.
